Book excerpt: Why taunt and flout us, as Beckett's writing does? Why discourage us from seeing, as Mark Rothko's paintings often can? Why immobilize and daze us, as Alain Resnais' films sometimes will? Why, Leo Bersnai and Ulysse Dutoit ask, would three acknowledged masters of their media make work deliberately opaque and inhospitable to an audience? This book shows how such crippling moves may signal a profoundly original - and profoundly anti-modernist - renunciation of art's authority.
